212-ZNBR Bearing Product Overview & Core Advantages
The 212-ZNBR is a single row deep groove ball bearing designed for robust performance in radial load applications. This metric bearing features a shielded design and a snap ring groove on the outer ring, offering excellent protection against contamination and simplified axial location within the housing. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides reliable operation and consistent performance for a wide range of industrial machinery.
212-ZNBR Bearing Model Code Explained, Specifications & Naming Convention
The model number 212-ZNBR can be broken down as follows:
- 212: Standard bearing series designation, indicating the dimensional series (light) and bore diameter (60mm).
- Z: Signifies a shielded (non-contact) configuration on one side, protecting the internal components from large particulate contaminants.
- N: Indicates a snap ring groove on the outer ring. This feature allows for secure axial positioning and simplifies housing design.
- BR: Denotes the use of chrome steel for the rings, balls, and cage, ensuring high strength and durability.
212-ZNBR Bearing Structural Features & Performance Benefits
- High Load Capacity: The deep groove raceway and chrome steel construction enable high radial dynamic load rating (12,612 lbf) and static load rating (11,240 lbf), making it suitable for demanding applications.
- Simplified Assembly & Location: The integrated snap ring groove eliminates the need for complex housing shoulders or end caps, reducing assembly time and cost.
- Contamination Protection: The shielded (Z) design effectively prevents the ingress of large particles, enhancing bearing service life in challenging environments.
- Standardized Precision: Manufactured to ABEC 1 | ISO P0 tolerance class with standard CN radial internal clearance, ensuring reliable, interchangeable performance.
- Wide Temperature Range: The all-steel construction allows for operation within a temperature range of -30°C to 120°C.
212-ZNBR Bearing Typical Application Areas
This versatile bearing is ideally suited for applications requiring reliable radial load support and easy axial location, including:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Pumps and Fans
- Material Handling Equipment
- Agricultural Machinery
- Automotive Components (e.g., alternators, idlers)
